A popular ‘short form’ of the aphorism often quoted to medical students during clinical rotations—‘when you hear hoofbeats, don’t think of zebras.’ This variation of ‘Sutton’s law’ is designed to teach students a logical approach to a diagnosis, since common things occur commonly and when one hears hoofbeats, one should first think of horses and exclude them in the differential diagnosis before thinking of the unusual causes—the zebras—of a particular clinical finding.
